The Difference Between Shrink Film And Stretch Film

图片
  After years in the packaging industry, Industrial Packaging frequently receives questions about shrink film and stretch film, especially: "What is the difference between them?"     One film can be used in a heat tunnel for packaging, while using the other this way could cause a fire. Understanding the differences is crucial when sourcing these materials. This article explains their distinctions and appropriate applications.   What Is Shrink Film?     Shrink film , also known as shrink wrap, is a polymer-based plastic packaging material, typically made from polyolefin, polyvinyl chloride (PVC), or polyethylene. When heated to a specific temperature, shrink film uniformly contracts to form a snug, protective layer around the product. Heat is typically applied using a heat gun or a heat tunnel.     In the heat tunnel process, the film is loosely sealed around the product with an L-bar sealer before being conveyed through the tunnel. As the pro...

Types of Shrink Film: PE, POF, and PVC

图片
Shrink film   is a flexible and durable plastic material widely used for wrapping and protecting products. Upon applying heat, it tightly conforms to the item's shape, ensuring a secure and tamper-evident seal. The most commonly used shrink films include polyvinyl chloride (PVC), polyolefin (POF), and polyethylene (PE). Each type offers unique benefits tailored to various applications.     Types of Shrink Film: PE, POF, and PVC   1. PVC Shrink Film     Polyvinyl chloride (PVC) shrink film is a widely used, cost-effective material for packaging non-food items.     Advantages   - High Clarity: PVC shrink film provides excellent transparency, making it perfect for retail display packaging.   - Cost-Effective: Compared to polyolefin (POF) film, PVC is a more affordable option for budget-conscious projects.   - High Shrinkage: It adheres tightly to product surfaces, ensuring a secure fit that resists slipping or loosening.   ...
